ful Improvements in Apparatus for Sup-= porting Train-Pipes, of whichthe following is .a specification.

My invention relates to' apparatus for supporting train pipes, and theinvention has forits object to provide a device for' supporting the endof a steam or air train- Y pipe section which Will permit or cause thepipe, or end of the pipe, to shift when the train goes around a curve soas to take off or decrease the strain on the train-pipe coupling, which,under some conditions, has al tendency to cause the coupler heads tobe-,

pipe to be rup- I y invention mightbe employed in connection Theinvention isintended particularly for; use in connection with train-pipesectionsg which are connected together by means of couplings, such, f0rexample, as the familiar 1 Sewall gravity coupli s, which automati-Ecally uncouple when so cient strain or pull; is exerted upon them. Itfrequently happens 5 come uncoupled or the hose tured or undulystrained.

that, when couplers of this type are used,

cause the coupling to be uncoupled. .Sev-

the wrong time. seeks to obviate the difficulty by a shifting of thepipe sections themselves, or portions of the same. Preferably, theshifting is automatically accomplished, as will be hereinafterdescribed, by a connection between i the pipe support and the drawbar ofthecar.

The invention, in a preferred embodiment,

is illustrated in the accompanying drawings, wh rein,

Figure 1 is a fragmentary end elevation of a railway passenger car; Fig.2 isan eleangle iron eral devices of one kind or another, ordi-i narilyin the nature of locks, have been de- 1 vised for overcoming thistendency of the. gravity coupler to automatically unlock at The presentinvention.

Like characters of reference indicate like parts in the several of thedrawings.

Referring to the drawings, in which is shown a portion ofthe end of asteel railway car of ordinary construction, 10 designates the drawbar ofthe car, provided with the coupler head 11, by means of which the cardscoupled to the next car in the train, the drawbar being shown assupported by a hanger 12. secured to the longitudinal girders or beams13 supporting the floor of the car, the drawbar having, as is usual,some capacity for lateral movement on the transverse pin 14, whichlatter is secured to the hanger 12 and extends through a slot 15 in thedrawba-r. It will be understo d that my plan taken on line 66 with otherconstructions of car and of draft gear.

16'designates a hanger which is secured by bolts 17 to the members 18 ofthe car underframe so that it preferably stands back of the drawbarhanger '12. Mounted on this hanger isthe movable or sliding pipe sup, 1port 19, shown in detail in Fig. 2, this deand particularly when thehose is relativelyfi large and stifi, the swinging motion of the cars ingoing around reverse curves will:

vice being preferably formed with the upstanding flanges 20 at each "endthereof, and being also preferably provided with the guides 21 on" itsunder surface (Fig. 4). 1

The steam train pipe 22 is shown as being secured to one of theflanges20 by meansof the pipeclip 23. .This connection is made somewhatloose, so as to allow for expansion and contraction of the pipe. Thesignal pipe 24 and the air-brake train pipe 25 are shown as secured inlike manner to the other flange 20 by similar clips.

The slide 19 is formed on its upper surface with lugs 26 whichstandoneon each side of the drawbar 10, so that the lateral shift of thedrawbarmoves the slidein onedirection or the other. The lugs normallystand a short distance away from the drawbar, so that the slighteroscillating movements of the drawbar are not communicated to the pipes.This is particularly desirable because preferably the several train-pipesections '22, 24, 25 are rigidly secured to the body of the car at theircenter portions, as, for example. by the hangers designated,respectively, 27, 28' and 29 in Fig. 6. These hangers are placed atpoints remote enough shifted as above described.

from the ends of the pipes so that the clasticityof the pipes permitsthe ends to be In Fig I have shown somewhat diagrammatically portions oftwo cars, des'ignated A- and 'B, respectively. The cars are shown asgoing over reverse curves -in the na'ted or diminished. They-alsoillustrate.

track, the rails of which track are indicated at C. For clearness, Ihave'shown in this view only the. steam train pipe sections and theircoupling, these sections being designated 22 and 22 and being shown asconnected by a coupling designated .30, which may be of any desireddesign and construction. 7

Figs. 5'and 6 illustrate the deflection of the ends; of the train pipesections, sothat the strain 'on the' couplings is either elimiapreferred arrangement for diminishing the strain onthepipe at the pointof attachment, 27, of the train pipe to the car. This is accomplished byproviding a fulcrumfor 23, so that the pipe is bowed, as shown by thedotted lines in Fig. 6,. and the strain the pipe between the point 27and the clip distributed along the pipe, instead of being entirely, oralmost entirely, at the point 27. The fulcrum consists of a hanger orloop 31. Thespace in the loop the diameter of the pipe.

-.As the devices, constructions and arrangements by which myinvention iscarried out will in any particular case depend somewhat upon theconstruction of car on which the invention is. used, I do notlimit'myself to the particulars shown. and described, except'asthesamejare made specific limitations oncertain of the claims herein- Ihave shown a device for supporting three train pipe sections, but itwill be un derstood that a greater or less number of pipes-might beemployed. 7
